Question 37 of 45
A wave has a wavelength of 10 m and a speed of 65 m/s. What is the frequency of this wave in Hz?
Hz
Enter your answer as a number
CA
9
O

frequency = 6.5 Hz

Explanation:

Given that the

Speed V = 65 m/s

Wavelength (λ) = 10m

Wave speed is the product of frequency and wavelength. That is,

V = fλ

Substitute V and (λ) into the formula to get frequency f

65 = 10f

Make f the subject of formula

f = 65/10

f = 6.5 Hz

Therefore, the frequency of this wave is 6.5 Hz?

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
